Abstract

The invention discloses a window shutter type reactor internal component which comprises an inner barrel and an outer barrel. The inner barrel is coaxially placed in an outer sleeve. The inner barrel is mainly composed of an inner barrel upper connecting pipe (2), inner window shutter plates (3) and an inner barrel lower connecting pipe (5). The inner barrel upper connecting pipe and the inner barrel lower connecting pipe are located at the upper end and the lower end of the inner barrel respectively. A plurality of layers of inner window shutter plates are evenly distributed on the outer circumference of the inner barrel. The outer barrel is mainly composed of an outer barrel upper connecting pipe (7), outer window shutter plates (9) and an outer barrel lower connecting pipe (10). The outer barrel upper connecting pipe and the outer barrel lower connecting pipe are located at the upper end and the lower end of the outer barrel respectively. A plurality of layers of outer window shutter plates are evenly distributed on the inner circumference of the outer barrel. According to the window shutter type reaction internal component, the problems of the catalyst granule running losses and bed dead volume of a radial flow reactor are effectively solved. The flow area is large, the bed pressure is reduced, the treatment capacity of the reactor can be improved, and the window shutter type reactor internal component has high adaptability to non-spherical reducing catalyst granules.

Description

technical field [0001] The invention belongs to the technical field of radial flow reactors, and mainly relates to a reactor internal component in contact with a fluid and a solid, especially a louvered reactor internal component, which is especially suitable for a louvered radial moving bed reactor. Background technique [0002] The radial flow reactor is a high-efficiency and energy-saving reactor form, which has the advantages of large fluid flow cross-sectional area, uniform gas / solid contact, and low bed resistance. The form and layout of the internal components are the core of the radial flow reactor. The most basic internal structure of the radial flow reactor is composed of two porous coaxial sleeves, the space between the two sleeves is used as a solid catalyst bed, and the fluid flows through the catalyst bed in the radial direction. According to its fluid flow form, it can be divided into Z-type flow of the feed fluid and the discharge fluid in the same direction...
